I was wondering if anyone has a pic of how far their driveshaft goes into their t56? I was looking at mine and I think it might be too short. I had it shortened when I installed the ls t56. Now I am thinking I might have measured wrong. It works fine but there's like an inch of shaft showing between the dust seal And the yoke.

 

Unless you put an LS T56 onto a Gen I/II block you should have used a stock length driveshaft. So it's probably short by however much you shortened it.

 

Take measurements.

Determine how far into the tailhousing bushing the yoke is inserted. That bushing is an inch or 1.5" wide. If it's into 100% of the width of the bushing, you're fine because the spline depth is more than adequate at that point.

 

I will snap a pic tomorrow. Back when I did the ls tranny on a lt1 I was one of the first, so there was no information out there. It just looks like it's not in far enough for some reason.

 

I Have an LS tranny and yoke is always in the boot seal, you can see any of the splines of the out put shaft. This is best picture I have.

 

Is this ok? Keep in mind seal is not what's showing, that's just a dust seal. The actual seal is flush with housing. So it looks like I have about a couple inches of shaft inside tranny.

 

looks about rights to me

 

you should knock the rust off or it will kill that seal.
